This is a topic I know well of.Ive lost many dear pets and the pain is so bad.Ive gotten better as I get older though.If I know a pet is going to die I just have to keep telling myself it's going to happen over and over and then when it does it's not as bad.But then I suppress the feelings of sadness until months and months later when I'm ready to deal with it and accept the fact they will never return.Man does it hurt.Luckily my geese and iguana can live a really really long time.
